I have Travelpro Walkabout Lite.......LOVE IT, but its BLACK....so this is what i do (its pretty ugly)

REALLY BRIGHT ORANGE TAPE on ALL handles
Min of TWO luggage tags (one Trip Advisor, one Other)
Globalbagtag.com tags
REALLY BRIGHT YELLOW "POM-POM"
my LARGE suitcase has a red tag: "I should be flying First Class"
Large suitcase also has my "medjetassist" tag

Of all the "stuff" on my suitcase, the yellow pom-pom makes the biggest diff.

Now, occasionally the locks come off...so I always carry at least ONE extra TSA lock and electrical wire ties.
